Abstract

1277173 Electro-photographic cleaning apparatus INTERNATIONAL BUSINESS MACHINES CORP 16 Nov 1970 [29 Dec 1969] 54354/70 Heading G2H Residual developer is cleaned from a drum 1 by pressurized gas supplied through an apertured tube 28 which is reciprocated along its axis. A vacuum source connected to a pipe 23 sucks away the removed developer. Tube 28 may be reciprocated by an A. C. electromagnetic arrangement Fig. 7 (not shown) and a similar arrangement, Fig. 8 (not shown) preferably provides additional tube movement by oscillating the tube about its axis through a limited angular displacement. The pressurized gas cleaner may be used in conjunction with a lamp or corona discharge device (not shown) or with a selectively operable brush (36) Fig. 5 (not shown) or with a selectively operable cleaning web (42), Fig. 6 (not shown) optionally impregnated with wax, solid or liquid solvent, or abrasive.
